Completely forgot to mention the One Page Dungeon Competition is going on again. I was asked to participate as a judge again this year, but I've just got too much going on. However, I'd encourage anyone with mapmaking skills and an ounce of creativity to give it a shot. There are some great prizes this year (like 40 or so!). You can get the full scoop at this link.
Here's the thing: the deadline is April 1st, so get your asses in gear if you want to be in the game. Last year, I got to see and judge a huge pile of fantastic entries...the sheer creativity out there is wonderful. But I think the participants themselves get a lot out of the exercise of distilling an adventure down to one page. I know I was impressed by the skills on display!
Good luck to all!
